SPECIFICATION forming part of Letters Patent No. 416,764, dated December 10, 1889.

i Application filed February 1,1889. Serial No. 228,368. (No model.)

To all whom it may concern.-

Be it? knownthat I, CHARLES D. ToWNE, a citizen of the United States, residing at Galesburg, county of Kalamazoo, State of Michigan, have invented a new and useful Elevator for Harvesting-Machines, of which the following is a specification.

This invention relates to that class of elevators which are employed on the platform upon which the grain or oth er vegetation falls when cut by the knives of the cutter-bar for moving it laterally on said platform and up the incline thereof to the place where it is collected into a bundle.

While the elevator may be employed in ordinary grain-reaping machines for elevating the grain, I have more particularly designed it for a corn-harvester.

The obj ect of this invention consists in the peculiar construction of a series of alternatelyreciprocating rakes and combining them with the horizontal and` inclined part of the platform, all as more fully described and claimed below.

In the drawings forming a part of this speciiication, Figure lis a plan View; Fig. 2, an enlarged section taken on a line with one of the reciprocating rakes; and Fig. 3 is an en- .larged broken detail of parts in Fig. 2 in pei'- spective.

Referring tothe lettered parts of the drawings, A A is the frame of the platform, which platform consists of the horizontal part B and the upwardly-inclined part D. rlhe reciprocating rakes consist of the toothed bar c on the horizontal part B of the platform, the inclined bar e (also bearing teeth) on the oblique part D of the platform, and the strap or link c at an angle less than the oblique angle of the bar e and greater than the horizontal angleof the part B of the platform, These parts le, e', and c are end to end with each other, the strap c being between the toothed bars e e', and is jointedly attached or hinged at each end to the ends of the bars e e. By means of the connecting 'strap or lilik c at the oblique angle, as described, when reciprocating motion is imparted to the horicramping and undue friction. `As many of as desired. Six are here shown, Fig. 1. When three alternating rakes move to the left, Fig. l, the corn or grain is carried in that direction the distance of said movement by the teeth d, which are thrown up by contact with the corn or grain, as in Figs. 2 and 3. While this action is taking place, the other rakes, which alternate with those just described, move to the right from beneath the corn or grain, and their teeth are tilted down by contact of their back edges with the corn or grain. Thus the of rakes finally deliver the grain or corn over the top of theinclined part D of the platform onto the carrier-arms h. As here shown, the rakes rest on the cross-bars .cof the platform in the spaces n; or the platform may beprovided `with grooves or channels in lieu of these spaces. The teeth d, the action of which is above described," are pivoted in a vertical opening in the castings at o. The back wall of these castings prevents the teeth from tilting too far back during the forward movement of the rakes, while the front limit to the tilting of the teeth isV the bar to which the casting is attached. Fig. 3.) In this figure the tooth cl is something in the form of a scalene triangle; but this is not essential, and even the casting @c may be dispensed with, so long as suitable teeth are pivoted to the barspof the rakes in a manner to tilt and be limited in their movements, as described. The rakes may be made of Wood or metal.

In Fig. l is shown a shaftt, having a series of double cranks. Aportion of the platform is broken away, showing two of the cranks. The front end of the horizontal part c of the rakes are individually attached to the respective cranks by bars a, pivoted at one end to the cranks and at the other end to the rakes. Other suitable means may be employed to eect the described movements of the reciprocating alternating sets of rakes.

claim, and desire to secure by Letters Patent of the United States, is i The combination of the platform consisting these reciprocating rakes may be employed alternate reciprocating movements of the sets (See dotted tooth d in Having thus described my invention,wha.t I
